What Causes strabismus?
The exact cause of strabismus is not fully understood. Six eye muscles, controlling each eye movement, are attached to the outside of each eye. In each eye, two muscles move the eye right or left. The other four muscles move it up or down or rotate the eye.
To line up and focus both eyes on a single target, all the muscles in each eye must be balanced and work together, the muscles in both eyes must be coordinated. The brain controls the eye muscles.
